The documentation I have on the 68040 says there are several important differences between the 68030 and the 68040 MMUs. One would appear to be that there are separate MMUs for data and instructions, another that pages can be designated as "writethrough, copyback, noncachable, or noncachable". I would really appreciate some source code I could study on this as well as any application notes. Also, will this require a 68040 Compiler/Assembler or can I just use some constants with a 68030 Compiler/Assembler. Thank you, Michael Goldman I
